Summary:
* You need TFTP and DHCP servers to load firmware and configs on the phones.
* The dedicated buttons can be made to work with Asterisk.
* There is an XML browser system for defining custom menus and services.

If you had any extra phones, and if I had a few evenings to spare, I'd
totally get into playing with these.  It looks like there's a lot of
potential there, and I've often wanted to work on an Asterisk-based
replacement for the (horrible and very expensive) Cisco Call Manager.
